I agree with dirkdj. Full throttle and 2500 or 2600 rpm to top of climb.
My favourite "utility" setting, which is worth remembering, is 19" 2300 rpm. That tends to give about 120 kt gear up, and is a good speed for holding and general manoeuvring.
The other useful rule of thumb is that a 1" reduction in MP gives about 100 fpm descent.
Enjoy.
